Pellet-based 3D printing has been gaining momentum across the manufacturing world, and for good reason. The biggest shift is flexibility. Unlike traditional filament printing, pellet extrusion uses raw thermoplastic pellets, often the same material used in injection moulding. That simple shift has opened the door to faster production speeds, broader material choice, and most notably, better sustainability.
Printing in-house with pellets is now a real option for teams who want to take control of prototyping, tooling or even production parts. For businesses looking to reduce outsourcing and shrink their footprint, this is a practical way to do both.Pellet systems also allow for faster build speeds and a wider range of materials, including softer or more complex polymers that can’t always be used in filament form. And because the material is more uniform, it’s easier to manage waste and recycle anything that doesn’t make the cut.
From a cost point of view, the numbers are hard to ignore. Using pellets can be significantly more affordable over time, especially when printing at scale. But it’s the combination of lower cost and reduced environmental impact that’s pushing more British manufacturers to consider this route.
In short, pellet-based 3D printing offers more than just speed or scale. It gives British manufacturers a chance to meet production goals and sustainability targets at the same time with fewer trade-offs and more control over how they build. And in today’s landscape, that’s not just helpful, it’s becoming essential.
